Title: Injection moulding of large plastic components
Inventor: BERELOVICH LAZER
IPC: B29C45/53
Filed: 1998-05-20
Abstract: A system for injection moulding of large plastics components in a single shot comprises an extruder and an accumulator fed from the extruder. The accumulator leads into the mould (14) via a mould valve (12) operative, when closed, to close the mould cavity substantially at the mould surface and also to close an outlet (20a) from the accumulator. The valve passage of the mould valve is of relatively large cross section, typically several centimetres or more which facilitates injection at relatively low pressures and also facilitates passage of stones and other particulate matter which may be present if the extrudate is composed of post-consumer recycled plastics.

Title: Gemstone setting
Inventor: HOFFMAN PAUL J
IPC: A44C17/04
Filed: 2000-01-11
Abstract: A gemstone setting is provided having channels into which grooved gemstones are snapped and secured. Each channel is provided with opposing, flexible prong members extending from the base of the gemstone setting. As the grooved gemstones are snapped into the channels, the prong members flex outwardly as the gemstones are pushed downwardly into the channels, such prong members snapping into engagement with the grooves on the gemstones to securely hold the gemstones within such channels. When the channels of the gemstone setting have been filled with gemstones, the gemstone setting is rendered invisible.

Abstract: A system for monitoring blood pressure within a blood vessel (12) of a living being. The system includes an implantable sensor (20) unit and an associated externally located energy application transceiver (24). The sensor unit is in the form of a housing (28) including a movable deflection member (76) and a tuned circuit (22) including an inductor coil (L) and a capacitor (C). The housing surrounds the wall of the blood vessel and includes a wall portion (42) arranged to flatten a portion of the periphery of the blood vessel. The deflection member extends through a slot (78) in the wall portion of the housing for engagement with only the flattened portion of the blood vessel to move in response to the pressure applied to the flattened portion of the blood vessel by the blood. The deflection member includes a ferrite core (74). The ferrite core is arranged to move with respect to the coil (70) in response to the movement of the deflection member, thereby changing the inductance of the tuned circuit. Electrical energy is provided from the transceiver unit to energize the tuned circuit of the sensor unit, which when energized provides a wireless electrical output signal representative of pressure changes within the blood vessel back to the transceiver. Since the deflection member only engages the flattened portion of the blood vessel the electrical output signal is linear with respect to blood pressure.
